Abstract
An imidazo [1,2-b]pyridazine compound of the formula (I):
wherein R1 is a halogen atom or a lower alkyl group optionally having substituent(s), R2 and R3 are, independently, a hydrogen atom, a lower alkyl group optionally having substituent(s), a cycloalkyl group or a phenyl group optionally having substituent(s) or R2 and R3 together with the adjacent nitrogen atom to which they bond may form a heterocyclic ring optionally having substituent(s), X is an oxygen atom or S(O)k (k is zero to two), a group
wherein R1 is a halogen atom or a lower alkyl group optionally having substituent(s), R2 and R3 are, independently, a hydrogen atom, a lower alkyl group optionally having substituent(s), a cycloalkyl group or a phenyl group optionally having substituent(s) or R2 and R3 together with the adjacent nitrogen atom to which they bond may form a heterocyclic ring optionally having substituent(s), X is an oxygen atom or S(O)k (k is zero to two), a group
